How do i forward an email to many people without showing their emails in the (To) blank?
Put your all addresses in "BCC" field
Reply:Use the bcc field for that


(if you use "to" or "cc" thay will see the addresses, but bcc stands for "blind carbon copy")
Reply:I tried the "bcc" method, but yahoo said to put at least one address in the "To" field. So I just put my e-mail which seems kind of ineffecient to me.
